Answer:
Part a) 
Part b) 
Step-by-step explanation:we know that
The volume of the sink (half sphere) is equal to

Part a) One cup has a diameter of 6 in. and a height of 8 in. How many cups of water must Michael scoop out of the sink with this cup to empty it?
The volume of the cylinder is equal to

we have
----> the radius is half the diameter

substitute the values

To find the number of cups divide the total volume of the sink by the volume of the cylinder

Round to the nearest whole number

Part b) One cup has a diameter of 10 in. and a height of 8 in. How many cups of water must Michael scoop out of the sink with this cup to empty it?
The volume of the cylinder is equal to

we have
----> the radius is half the diameter

substitute the values

To find the number of cups divide the total volume of the sink by the volume of the cylinder

Answer:
13.86
Step-by-step explanation:
(-2.2)(1.5)(-4.2) =
Use a calculator. Start with -2.2 * 1.5.
= (-3.3)(-4.2)
= 13.86
You have posted 2 separate questions here. Please, next time, separate them with a blank line:
<span>A circle has an area of 81 3.14 units . what is the diameter in terms of 3.14?
I'd prefer you write this as
"</span><span>A circle has an area of 81 pi units . what is the diameter in terms of pi?
Area of a circle = A = pi*r^2. Note that r= diameter / 2. Here, the area is 81 pi square units, or 9^2 * pi square units, which means that the radius is 9 units. The diameter is then 2(9 units) = 18 units.
Your second question, separated from the first, is:
"</span><span>a circle has an area of 81 Pi square units what is the diameter of the circle?"
</span><span>
Use the following formula or formulas: d = 2*r; A = pi*r^2; A = pi*(d/2)^2. Find r first, and then find d.

Answer:
Discount = $10
Sales Price = $30
Step-by-step explanation:
Discount
= 25% of marked price
= 25% x $40
= (25/100) x 40
= $10
Sales price = Marked price - Discount = $40 - $10 = $30
Ok this is really easy if you thinl about it
so every ounce is how many servings?
well all you do is divide 72 by 12
happy solving :)
